Application filed June 12,

To all wlw/n, it may Cof/warn.'

Be it known that CLARK N. VlsNnn, a citizen of the United States, and a resident of New NUrleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Picker-Heads; and 1 do hereby declare the following to be a full, clear, and exact de-l scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Y This invention relates to improvements in cotton pickers and more particularly to an improved picker head, the object of the invention beingto simplify the construction and improve the efficiency of picker heads of the type to which my invention relates.

l/Vith this and other objects in view, the invention consists'in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings; Figure 1 is an elevation with one side of the frame or casing removed; Fig. 2 `is a side yelevation of the side ofthe frame or casing omitted from Fig. 1; Fig. 3 is a sectional view, partly in elevation; Fig. 'l is a plan viewof the pin carrier, and Fig. 5 is a view of a modification.

rllhe frame or casing 1 of my improved picker head comprises side plates 2, 3 which are spaced apartV and suitably secured. These side plates are made with enlargementsy el', 5', the enlargement d being made with a part '6 extending to the plate 5, said enlargements and the part 6 forming a chamber 7 open at both ends. The enlargements 4 5 are so formed that they vprovide a connection 8 which'will Yreceive and constitute a coupling for a discharge tube 9 to communicate with one end of the chamber 7.

The side plate 2 may be made on its inner side with an annular enlargement 10 and a circular' groove 11, to receive loosely one end of a rotary cylinder 12, the other end of said cylinder loosely entering a circular groove 11@L in the side plate 3 and mounted on an annular enlargement 13 projecting from the inner face of the other side plate 3, and said cylinder is thus mounted under the chamber 7.

The rotary cylinder 12 is provided with an annular or peripheral flange 14 which, in the construction shown in Figs. 1 and 3,

may be located centrally between the ends of the cylinder.

`All operating shaft 15 passes through the 4 cylinder 12 and through the side plates and 3. .An antifriction bearing device 16 isprovided on the outer' face of the side plate 4l for the end portion of the shaft 15 and an .antifriction' bearing device 17 is located in a recess in theinner enlargement 13 of the side plate 8'for said shaft.' The shaft 15 projects beyond the side plate 3 for connection withA a motor (not shown) which may be located within an annular flange 18 on said side, plate 3. j

The cylinder 12 is provided thereinwith a transverse bar (preferably angular in cross section) forming spokes 19` and an intermediate hub `portion A2O `for the accommodation of the driving shaft, to which latter, the .hub 2O is secured in any suitable manner. Thecylinder12 with its peripheral flange 111' and spokes 19 and hub 20 may be made in a single piece sol that these parts are integral with each other. Y

rl`he spokes 19 serve as guides for a carrier 21 having diametrically flanges 22. Picker pins 23 are secured to the flanges 22 of the carrier'1,'said pins projecting respectively, in opposite directions and passing freely through the wall of the cylinder and through holes in the annular flange 14,.- Thus it' will be seen that the picker pins will be so disposed that ifl extended rearwardly beyond theirconnection with the carrier they would be parallel with each other.. These picker pins maybe beveled at their free ends andjtheyoperate (when the cylinder' is rotated) as hooks tok pickthe cotton from the bolls and deliver it, through the chamber 7 -to the 'discharge tube 9.

rllhe body of the carrier 21 may be made cylindrical in form and is provided at one end with a pair of lugs or projections 24, to receive between them, a cam 25 projecting inwardly from the side pl-ate 2,so that when the shaft 15 and cylinder 12 are rotated, the carrier 19 will be caused to reciprocate within the cylinder and cause the respective picker pins to be alternately projected and withdrawn. Y

It will be seen that when the shaft 15 and cylinder 12 are rotated, one of the picker pins will be projected as it approaches the forward portion of thewhead and remove the cotton from the boll. When opposite the projecting portion of this picker pin is ,recede and release the cotton so that the latter may be drawn, by suction, through the discharge tube 9. It will be understood that the two picker pins operate in succession in the manner above explained.

By providing the cylinder with the peripheral flange 14C and causing the picker pins to pass through and project beyond said flange, I am enabled to insure a maximum effective working stroke of said pins and'to provide passages, such as indicated at 26, through which the air (caused by the suction through the tube 9) may pass, this air entering the picker head from behind the picker pin (as viewed in Fig. l) and thus facilitating and insuring the withdrawal of the cotton from the picker pin and the entrance of such cotton into the discharge tube 9.

Instead of providing a cylinder having a single peripheral flange and employing only two picker pins, a cylinder 27 such as shown in Fig. 5, having two annular flanges 28 and four picker pins 29, may be employed.

Various changes might be made in the details of construction of my invention Without departing from the spirit thereof or limiting its scope, and-hence I do not wish to restrict myself to` the precise details herein set forth.v

Having fully described my invention, what I claim as new and desire to secure by Letters-Patent, is

l. In a picker head, the combination with ,a frame provided withi a suction tube con-v nection, of a rotary cylinder mounted in said frame, said cylinder having a peripheral flange, picker pins passing through the wall of the cylinder and through said peripheral flange, and means for causing said picker pins. to be projected and withdrawn during the rotation of the cylinder.

2. fn a picker head, vthe combination with a frame providedV with a suction tube connection, of a rotary cylinder mounted in said frame, said cylinder having a periph eral flange, a reciprocatory member within tated, a reciprocatory carrier mounted in.

said cylinder, picker pins secured to said carrier and projecting respectively in opposite directions through the wall of the cylinder and through said peripheral flange, and means for causing said carrier to reciprocate when the cylinder is rotated.

4. In a picker head, the combination with a frame provided with a suction tube connection, of a rotary structure comprising, in a single piece, a rotary cylinder having a peripheral flange, a hub'and spokes con.

necting said hub with the wall of the cylinder, a reciprocatory carrier within said cylinder and guided by said spokes, picker pins secured to said carrier and passing freely through the wall of the cylinder and through said peripheral flange, a driving shaft secured to the hub of the cylinder, and means for causing the carrier to recipe rocate when the cylinder is rotated.

5. In a picker head, the combination with a frame having a chamber open at both ends, and a suction tube connection communicating with one end of said chamber, of a rotary cylinder mounted in the frame, under said chamber and having a peripheral flange, picker pins passing through the wall of the cylinder and through the peripheral flange thereof, and means for causing said pins to be projected and withdrawn when the cylinder is rotated.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses. Y
